Issue

When running poetry run python (or poetry shell/install/lock ...), I get the following warning:

/Users/nantas/Library/Application Support/pypoetry/venv/lib/python3.9/site-packages/setuptools/command/install.py:34: SetuptoolsDeprecationWarning: setup.py install is deprecated. Use build and pip and other standards-based tools.
  warnings.warn(

This warning is then present across any invocations of poetry run python. However inside a sourced shell -- i.e. after poetry shell -- running python does not produce the warning (which makes me think it's an issue with the poetry build that is pulled by install-poetry.py).

Interestingly, though, simply running poetry does not produce the warning.

To install poetry I did:

curl -sSL https://install.python-poetry.org | POETRY_VERSION=1.2.0a2 python3 -

with python3 being:

$ which python3                                                                                            
/opt/homebrew/bin/python3

The problem was mentioned in #4085, but this seems different enough to warrant a separate issue for discoverability.

it is different from #5157?

Closing this as a duplicate of #5157
